The DCF-TM-25/400P-08 is a large-mode-area (LMA), double-clad, thulium-doped fiber featuring an optimized pedestal core design for high-power operation in the 1.9 – 2.1 µm wavelenght range. With a 25 µm core and a 400 µm pump cladding, it delivers excellent beam quality, high brightness, and efficient pump absorption, making it an ideal gain medium for high-power fiber lasers and amplifiers.
